        Never heard of this before, looks cool. Wish I had that when I was taking calculus lol

  Just x²+c, but when you’re integrating between limits the +c doesn’t matter - so you’re just left with the difference between 13² and 10²…

    It isn’t that it doesn’t matter, constant of integration is only used for undefined integrals.

      I think it’s “indefinite” not “undefined.”

      The reason it doesn’t matter/is only used for indefinite integrals is just that it gets subtracted out when you evaluate at the limits.of integration, so it always goes away (but it’s still there).

        I think it’s “indefinite” not “undefined” (at least in English).

        You are correct, it has been at least then years since my calculus classes which I took in a language that isn’t English.

  The integral of 2xdx is x^2 + c, and it’s evaluated from 10 to 13. So you’d have the following:

  (13^2 + c) - (10^2 + c).

  The c’s cancel. I’ll leave you to do the rest…
